安装yum

sudo apt-get update
sudo apt install yum

Linux系统(Ubuntu)中使用国内的源地址

• 源地址列表文件路径

  ubuntu系统的源列表配置文件的路径是：/etc/apt/ sources.list

为了在替换前留个备份，可以执行命令做个备份：

cp /etc/apt/sources.list /etc/apt/sources.list-bak

• 源地址列表文件的替换

  不同的版本，sources.list里的url是不同的，主要是版本好不一样，例如ubuntu14.04的代号是trusty ，而ubuntu16.04是 xenial。

具体查看方法是执行命令：lsb_release -a 回车

返回的Codename就是版本代号

ubuntu14.04版本

将/etc/apt/ sources.list的内容替换为：

deb http://mirrors.aliyun.com/ubuntu/ trusty main multiverse restricted universe

deb http://mirrors.aliyun.com/ubuntu/ trusty-backports main multiverse restricted universe

deb http://mirrors.aliyun.com/ubuntu/ trusty-proposed main multiverse restricted universe
